SHEARS FOR CUTTING AND TRIMMING GRASS AND HEDG-ES.

Application filed N'ovembier 17, 1924. Serial No. 750,335.

To @ZZ whom, t may concern.' y

Be it known that I, JAMES T 11' 'oMiAs S'rrr'r, oit Nemegos, in the district ot Sudbury, in the Province ot' Ontario, Canada, asubject or" the King ot Great Britain, have invented certain new and usei'ul Improvements in vShears for Cutting and rI`rimming (irrass and Hedges, of which the following is a specification.

My invention relates to improvements in shears for cutting and trimming grass and hedges, in which two knives are fastened together by a rivet, and operated by handles attached to the said knives; and the object of my improvement is to provide a double cutting action :tor such shears, whereby the knives will cut not only when the handles are drawn together, but will also cut when the handles are drawn apart.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which Fig. l is a plan view of the shears, the handles positioned at the end 01"' their outward stroke;

Fig. 2 a side elevation of the shears;

Fig. 3 a plan view ol the shears with the handles positioned at the end ot their inward stroke; and

Fig. fla sectional detail ot' the mechanism which adjusts the hearing ot the knives.

Similar letters refer to similar parts throughout the several views.

The handles L a, blades c c, rivet (Z, spring e, set screw 7, bars Z) b, and rivets g g, constitute -the shears. The handles a a, are litted on the bawrs b b, and the latter are secured by rivets g g, to the blades c c. The blades 0 c, are sharpened on all edges except the rounded edge 7L h, at the base of the blades. lVhen the handles a u, as in Figure l are drawn together the blades c c, are drawn together and the cutting edges 7c 7s, of the blades c o, are brought into operation, the inward movement of the handles a a, finishing as shown in Figure 3. Zhen the handles a a, as in Figure 3 are drawn apart the blades c c, are drawn together' and the cutting edges -Z Z, are brought into operation, the outward stroke ot the handles finishing as in Figure l.

rllhe spring e, andk set screw f, serve to regulate and maintain I am aware that `pruning shears have been proposed which cut both when the handles are moved together and when' they are spreadl apart, but such shears have not been made with two double edged blades adapt-- ed to pass one another so that the right hand edge of one blade may be brought into cooperative relationship with the lett hand edge ot' the other and vice versa. Nor have such double edged blades been symmetrically disposed relativel to the handles, both of which arrangement-s are essential in double cutting grass shears since the line ot cutting must always have a fixed direction rela.- tive to the operator, and for the greatest convenience in operation the line of cutting, when rearwardly projected, should bisect the angle between the handles.

Nor have shears been proposed in which the handles are so positioned relative to the blades that each handle is movable between two extreme positions at its own side et' the line of cut whereby cutting with one set ot edges takes place as the handles are spread apart and with the other edges as they are brought together.

vWhat I claim is 1. In grass cutting shears, a pair ot double-edged blades pivotally connected at a point in a line intermediate ot their cutting edges, the blades being adapted to pass one another so that the right hand edge ot one blade may be brought into co-operative relationship with the left hand edge of the other or vice versa, the handles being pesitioned relative to the blades so that each handle is movable between two extreme positions at its own side of the line of cut, whereby cutting with one set of edges takes place as the handles are spread apart and with the other set of edges as they are brought together. i

2. In grass cutting shears, a pair ot handles; a pair of double-edged blades pivotally connected at a point ina liner intermediate ot their cutting edges and symmetrically disposed relative to the handles, the blades being adapted to pass one ano ther so that the (Q Y i 1,533,479

right hand edge of oney blade may be brought into (3o-operative relationship with the left hand edge of the other or vice versa, the handles being positioned relative to the blades so that each handle is movable between two extreme positions at its Own side of the line of ont, whereby enttingvith one set of edges takes place as the handles are spread apart and with the other set of edges as they are brought together. lo
